Anyone know how to reduce/eliminate razor burn on neck?

I know the obvious answer is not to shave but it is my only option now. Too much to tweeze, too much area to wax (and i am embarassed to go anywhere to get it done;-), I have even tried laser but after much $$ and time and pain (it hurts) It is just as bad!
Please any help would be so appreciated, it is starting to be really obvious that i shave my neck and chin!! This is such a delicate topic, I am so glad this site addresses it and gives women a chance to share! Thank you!
